Abstract

The paper provides information about the reliability and accuracy of the results of nu- merical simulation of stress waves in solid deformable environment. The problem of elastic reflection of stress waves from the free surface of the plate. The task is implemented using the finite element method in movements. The comparison is made with results of the analytical solution at the front of the flat longitudinal wave. The studied problem is presented in the form of an infinite plate

Abstract

The article deals with evaluation of reliability and accuracy of results of solution of dif- ferent tasks under nonstationary dynamic wave impacts made using the finite element method in displacements. Comparison is made with the results of the analytical decision and dynamic photo of elasticity. The investigated problem is represented in the form of buildings with a base at the influence of nonstationary stress wave
